A Michigan health system says an employee's laptop containing unsecured personal health information was stolen from an unlocked office.
Spokesman David Olejarz tells The Detroit News that Henry Ford Health System isn't saying how many people are affected, but it has notified male patients who received prostate services between 1997 and 2008.
Federal law requires health care organizations that suspect a breach of unsecured health information to notify patients within 60 days.
The News reports Tuesday the laptop didn't contain Social Security numbers, health insurance numbers or patients' electronic medical records. But Henry Ford says the laptop did have some personal information.
The health system says the laptop was password-protected, but patient information could possibly be viewed.
The Detroit Free Press says the theft took place on Sept. 24.
